One year ago, at just 23 years old, Yordano Ventura became one of the youngest pitchers to start a World Series game in the last 30 years. The presence of a young starter in the World Series is not a completely rare phenomenon, naturally. Ventura, for his part, was the 64th pitcher in Series history to make a start before turning 24 years old, per Baseball Reference Play Index. Noah Syndergaard is set to be the 65th when the two face off this evening. Widening the criteria a little, one finds that 105 pitchers have made World Series starters before turning 25 years old.
